CLOCK.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed April 13, 1909. Serial No. 489,632.

To all whom it may concern:

to it known that I, ABRAHAM M. Yunnan, a citizen of the United States,residing at Perkasie, county of Bucks, and State of Pennsylvania, haveinvented a. new and useful Clock, of which the following is aspecification.

My invention consists of improvements in clocks, embodying means foradjusting the verge of the escapement so that the pallets of the samemay be set properly relatively to the teeth of the escapement wheel, andnew surfaces on said pallets may be presented to said teeth as the.prior contacting surfaces are worn, thus overcoming lost motion andcausing in either case easy-running of the clock.

For the purpose of explaining the inven tion, the accompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be varied, and so it is to beunderstood that the invention is not limited to the specific arrangementand organization shown and described.

Figure 1 represents a front view of a portion of a clock embodying myinvention. Fig. 2 represents a partial side elevation and partialsection of a portion on line 00-.60, Fig. 1. Fig. 3 represents a sideelevation of the verge support detached. Fig. 4 represents a section ofa portion on line y-y, Fig. 1. Fig. 5 represents a side elevation of aportion of the frame. Fig. 6 represents a section of a portion on line2-2, Fig. 1. Figs. 7 and 8 represent sections of modifications of theadjustable shaft and verge-bearings.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawing :-A designates the frame of a clock.

B designates one of the wheels of the train, the shaft C thereof havingits ends mounted in the bushings D, the latter being movably containedin the collars E, which are firmly secured to the frame in openingstherein.

On the peripheries of the bushings are the longitudinally extendingslots F, in which are received the points of the set screws G, which arefitted in the collars E and serve to hold said bushings in set position,according to the requirements of the shaft, and when the latter isadjusted, the screws G are tight ened, the effect of which is evident.As the ends of the shaft are worn, the screws are loosened and thebushings moved to the required extent, when the screws are againtightened, thus taking-up the lost motion and causing regularity in therotation of the shaft. Furthermore, by withdrawin the bushings, theshaft C and consequently the wheel B may be readily removed and easilyreapplied.

H designates the escapement wheel, and J the anchor or verge therefor,both of usual form. The verge is mounted on the pin K, which is freelyfitted in an opening in the arm L, which is secured to an adjacentportion of the frame A.

The pin K has a shoulder M, against which the verge is rested, while theportion of the former in the opening in the arm L is engaged by the setscrew N, which is titted in the wall of said. opening and adapted totighten against said pin, it being evident that as the pallets of theverge wear, especially where they contact with the teeth of theescapement, the verge may be moved in and out, the screw N beingpreviously loosened, the verge remaining in contact with the shoulder M.When the verge is adjusted as desired, the screw N is tightened, and sothe former retains its newly set position.

P designates the arbor of the spring Q, and R designates the post withwhich said spring is connected. The arbor P is mounted in the collar S,which is connected with the plate T, said collar occupying the open slotU in the adjacent member of the frame A. By this provision, when theplate is unscrewed or loosened from the frame, the collar S may bereadily removed from the frame A, thus adapting of the convenientdisconnection of the said spring and its arbor from the frame withoutdisturbing the other members of the clock or disintegrating the frame,and as is evident admitting of the restoration of said spring, its arborand the collar to the frame.

The post R is retained by the screws V, which are passed through theadjacent portions of the frame into the ends of said post, thus securingthe latter in position, while admitting of the convenient removal oi thesame when a spring is to be displaced.

In Fig. T, I show a bushing i) in lieu of one of the bushings D, thesame being exteriorly threaded and engaging with threads interiorly ofthe collar E, so as to be screwed in and out and thus be adapted for theadjustment and take-up of the shaft that is mounted in the bushing.

In Fig. 8, I show a threaded pin or screw K in lieu of the pin K, thesame having a nut K thereon, the latter being adapted to be tightenedagainst the arm L in which said screw is fitted thus retaining said pinin the adjusted position of the verge, which latter is fitted on thenut-threaded portion of said screw K and rested against the shoulder Mthereof similar to the shoulder M, the

verge being thus capable of adjustment similar to that shown 111 Fig.-l-.

Having thus described my invention, what I I claim as new and desire tosecure by Letters Patent, is

1. In a clock a verge, a pin on which the same is mounted, an armeonneetible with the frame of the clock, said pin being adjustably heldon said arm for movement in the direction of its length, and a set screwon said arm adapted. to engage said pin.

2. In a clock, a verge, a pin on which the
